I cannot look through 505 pages of posts. Is anyone using this lens with a Canon teleconverter 1.4x iii or a 2x iii? If you are how is the image quality?

Previous page, post #7555.
I posted pics with 2X TC as well as stacked 2X and 1.4x TC.

Like this 1.4 III

Chuck that owl was about a year ago. This is from the other day.

I'll see if I can get some un or lightly cropped shots over the next few days.

From your shots I'd say it works just fine !! Thank you.

Everyone is... 40 foot.. 30 feet above them, hand held shot down an embankment ... cropped to the very few pixels in the centre of the image!!!

Its a question that is timeless... Dont mind answering the call... I have thousands of um

As Doug from... Forged in Fire... Would say.... It Will Kill lol

Nice images Jeff, especially the Hummingbird shots. A-1, top notch!!

Since we're on the subject of extenders here's a question.

I have a 1.4 II extender that I use occasionally with the 7D MK II and the 100‑400mm f/4.5‑5.6L IS II USM. The 1.4 II stays in the bag most of the time. In most cases I'm just not happy with the image quality. I was wondering with the 1.4 III if there would be any improvement in image quality? Enough improvement to justify the cost?

Some say yes... Others say not so much... Shooting with the extender kinda doubles the amount of motion blur you could get in your image. If you up your shutter or skills just a bit it all comes together. I would regularly take a camera out of the hands of someone saying their camera was not right and shoot the moon handheld and hand it back to them. its all about ( yes I call it Trigger control ) I know some wonder how to get trigger from a camera but I guess they dont have a gun back ground.. And following through. Meaning don't just snap. yes its just a handheld shot of the moon but it has detail.. somewhat.

And I think..Not all cameras and lens belong and or do well together. but could on a different copy. They just aren't all exactly the same. I've used 9 7DII's and they were all different. Your camera and the 100-400LII may work wonderfully together.

just the head cut out of that

Own all of them,,,much prefer using the 1.4x . seem to get better results with F9-F10,,and 1200+ shutter speed. and of course you need good light and a steadier hand. Don,t get as many keepers at all with the 2X,,,find a tripod increaser rate with 2x but i seldom use a tripod.

Thanks for the reply Jeff. Kind of what I expected, some will say yes and others not so much. I guess some of it may depend on the copy of camera/lens combination and as well as the skills and technique of the user.

Great moon shot btw.

Very impressive shots when you have the right environment. I won't be hesitant now to get the 2x.

I have like 8 terabyte of example's... Wasted more than a couple camera's on wildlife. I have never used the 2x
